Title: Signal demodulation circuit
Inventor: BABA KYOJI
IPC: H04N9/64
Filed: 1985-10-23
Abstract: PURPOSE:To secure the stable color balance of a demodulating output signal by a multiplier by muting the input of the multiplier that forms the demodulating output signal of SECAM system with the non-carrier part of an input signal to be demodulated. CONSTITUTION:The carrier chrominance signal of a simultaneous color difference signal added on a terminal 20 is supplied to a color saturation control circuit 22 and a variable phase shifter 23 through a limiter 21. The variable phase shifter 23 performs the phase shift of the carrier chrominance signal by 90 deg. and supplies it to a multiplier 25. To the multiplier 25, an output signal from the color saturation control circuit 22 has been supplied through a muting switch 24, and by multiplying the signal by the signal from the variable phase shifter 23, the color difference signal is demodulated. At such a case, the muting switch 24 is switched and controlled with a muting pulse which is formed with an AND between the horizontal retrace pulse of an input SECAM signal and a burst gate pulse.

Title: Distortion measuring method and device
Inventor: HOSHINO HIROYUKI
IPC: G02B6/00
Filed: 1994-10-03
Abstract: PURPOSE: To easily control measurement sensitivity to a constant design value in terms of the mass production of a measuring instrument and make uniform measurement sensitivity and achieve a high sensitivity. CONSTITUTION: Light is applied from a light source 8 to a Bragg reflection type waveguide 1 via a directionality coupler 6. When incidence waves return after they are reflected from the Bragg reflection type waveguide 1, only a specific spectrum determined by the relationship between the Bragg lattice and the wavelength of light wave becomes reflection light. When the waveguide 1 is deformed due to strain, the Bragg lattice of the waveguide 1 fluctuates by the same rate so that the center value of the spectrum of reflection light fluctuates. The reflection light from the Bragg reflection type waveguide 1 passes through the directionality coupler 6, is separated by a light branching equipment 7, passes through optical fibers 10 and 11 with mutually different lengths and reaches an interferometer, thus creating interference fringes.  When the wavelength of the reflection light from the Bragg type reflection waveguide 1 changes, the position of the interference fringes moves so that the move of the interference fringes can be captured and is converted to strain.

Filed: 1983-12-19
Abstract: PURPOSE:To enable the introduction of a jet stream into an ionization chamber without bringing said jet stream into contact with a peripheral wall surface even if the directionality of said jet stream is slightly shifted, by providing a ring shaped nozzle. CONSTITUTION:The diameter of the connection part with the connection path 11 of a low pressure chamber 4 is gradually throttled to allow the gas in the lower pressure chamber 4 to smoothly flow into the path 11 and a ring shaped nozzle 13 is provided so as to surround the path of the jet stream of the outflow liquid injected from an injection nozzle 5. The blow-off port of the nozzle 13 is directed to the path 11 and auxiliary gas heated to an appropriate temp. by a heater 14 is supplied through a flow control valve 15. The gas stream generated from the ring shaped nozzle 13 is flowed toward an ionization chamber 2 so as to enclose the jet stream along the inner walls of the low pressure chamber 4 and the path 11. Therefore, even when the directionality of the jet stream is slightly shifted, the jet stream guided so as to be enclosed by the gas stream is prevented from the contact with the peripheral wall and introduced into the ionization chamber 2 along with the gas stream.

Title: Copying device
Inventor: WATANABE TSUTOMU
IPC: G03G15/043
Filed: 1985-10-28
Abstract: PURPOSE:To obtain a copied picture image in true focus even when the original is uneven by measuring the distance from the image forming reference plane of an original placed on an original setting table with the face to be copied facing upward to the face to be copied before exposing and keeping the length of light path from the face to be copied to a photosensitive body according to the measured value. CONSTITUTION:A book 1 is placed on a book cassette 2 mounted on an original setting table 5 with the face to be copied (f) facing upward. When a copy command switch is depressed, the original setting table 5 starts moving at a constant speed, and the distance between a distance measuring device 7 and the face to be copied (f) of the book 1 is measured, and the measured value is outputted to a controlling circuit 30. The rate of change of the distance from the image forming reference plane of the original to the face to be copied is calculated from positional information of output of the distance measuring means and exposure scanning direction of the distance measuring means. When an area in which the rate of change is large and does not require copying is calculated, feeding of transfer paper is delayed for the area.

Title: Stake joint and stake guide
Inventor: HARANO TOKIKO
IPC: A01G9/14
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a stake guide to be used in driving a wooden or synthetic resin stake used in an agricultural simple greenhouse, gardening site, construction site, guardfence, fence, etc., and to provide a stake joint to be used in jointing two stakes to each other. SOLUTION: This stake joint 1 to be used in jointing two stakes 7, 7 to each other has an engagement portion 2 to be fitted on one stake 7, a junction 4 to be jointed to the other stake 7, and a portion 3 to be hit and to transmit the resulting impact therethrough to the stake 7. A stake using the above joint and guide has the following advantages: when the stake is driven, because its head is not hit directly, the damage of the stake head is slight, therefore enabling corrosion advancement from the stake head to be prevented, in particular in the case of a wooden stake;  besides, because the length of the stake is adjustable to such a length as to be easy to operate, for example, a level at or lower than the height of the waist of a relevant operator, the stake can be surely driven even at a place inadequate in footing somewhat along with obviating the necessity of using a stepladder or the like, therefore enabling work safety to be improved.
